Line a cookie sheet with parchment paper or aluminum foil (do it; this stuff gets sticky). Arrange your pretzels thereon. My brother used those waffle pretzels, which lined up beautifully. However, they cost more than twice as much so I went traditional with mine.

In a saucepan, melt your butter, then add the sugar and stir until dissolved. Bring to a gentle boil and let it boil for just a minute (it should thicken just a bit and the bubbles should get a bit bigger).

Drizzle this over your pretzels and put it in the oven (be careful because your pan will already by a bit hot from the hot caramel). Bake at 350 for 5 minutes.

Take out and put the chocolate chips on top. Let them melt (you can throw them back in the oven for a minute--only a minute--or you can just let them melt on the hot caramel). Gently spread the chocolate around.

Sprinkle on salt if using, or sprinkles or decorative colorful melting chocolate.
